| Abstract: | Objective To study technology of extracting Aucubin from Emei Aucuba by supercritical CO2, and set base to study Aucuba futher. Methods Using supercritical CO2 to extract Aucubin from Emei Aucuba and compared with refluxing extraction. Results When the separating pressure was 6.5MPa, separating temperature was at 55℃, the flow rate of CO2 was controled at 25.0 L/h with taking ethanol of 95% as modifier, the optimal extractive condition was temperature 40℃, pressure is 20 Mpa and extracting time for 1.5 hr., and the extraction rate of aucubin was 2.85mg/g. Conclution It's convenient of extraction of Aucubin from Emei Aucuba by supercritical CO2, and the extraction rate is higher. So it can be extended. |
